Hi, I'm using a self defined fitting functions for a harmonic fit of a temperature series. In the last year it works very fine. Now I got the following error message: Error! Your fitting function is not generating values. Check that your data set has values. If you have a User-defined function: 1) Check your expression for syntax errors 2) Make sure that you are using the Y-Script or Equation form
Do you mind sharing your project and the user-defined fitting function.
Could you check your XY data and make sure there are values (numeric). Also open your user-defined fitting function via Tools: Fitting Function Builder. On 1st page, check what function type did u use, expression, Y-Script or Equation form. Check the hint of what syntax should be used to define function body and parameter.
On the page with function body, enter some x value and click the running man to make quick check to make sure the function is defined correctly.
